Specification of Letters Patent.

Patented July 28, 1914.

Application filed October 16, 1913. Serial No. 795,580.

To all whom it may concern Be it known that I, MARTIN PnAnsoN, a citizenof the United States of America, residing at Los Angeles, county of LosAngeles, State of California, have invented a certain new and usefulRotatable Float Apand I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to rotatable float apparatus for flying machines,and it may be said to consist in the provision of the novel andadvantageous features and in the novel and improved construction,arrangement and combination of parts and devices as will be apparentfrom the description and claims'which follow hereinafter.

' @neo'bject of the invention is to provide noveli'aind improvedapparatus of the class specified which is adapted to exert elevating andsustaining efl'ects on the flying machine.

Another object of the invention is to provide a novelandimprovedconstruction for the collapsible floats and also foradjusting the floats.

Further objects of the invention are to provide novel and improvedapparatus of the class specified, which is simple in construction,strong and durable, convenient to use, easy to a j weight and effectivein action.

Other objects and the advantages of the invention will be apparent tothose skilled in the art from a consideration of the followingdescription of the preferred form of construction of the apparatus,taken in connection with the accompanying drawings in which- Figure 1 isa partly broken and sectional view taken on the line 11 of Fig. 4 andshowing a flying machine having the invention applied thereto; Fig. 2 isan enlarged broken and sectional view taken on the line 2-2 of Fig. 1;Fig. 3 is a sectional view of one of the floats taken on the line 3-3 ofFig. 2; Fig. 4 is a sectional view of the flying machine taken on theline 4- 1 of Fig. 1 and showing the rotatable float apparatus in plan;Fig. 5 is an enlarged broken and sectional view taken on the line 5-5 ofFig. 4; Fig. 6 is a fragmentary plan view of the float apparatus.showing one of the floats in. inflated position; Fig. 7 is an enlargedbroken and sectional view taken on ustand operate, light in' broken andsectional view taken on the line 8-8 of Fig. 4 and showing the lever andnotched sector for adjusting the float in pos tion; and Fig. 9 is abroken and sectional view taken on the line 99 of Fig. 1 and showing,the braking device.

The flying machine 10 may be of any suit-- able or approved formthatshown being fully described in Patent No. 1074288, dated September 30,1913and is provided on the tight compartment 12 for the operator andpassengers. A ring 13 is rotatively mounted on the frame 11 adjacent tothe compartment 12, and it has mounted thereon the collapsible floats 14which are adapted to exert elevating and sustaining effects on theflying machine. The ring 13 is provided with inwardlv projecting flanges15 and 16 and it is held in position on the frame 11 by means ofbrackets 17 which are suitably aflixed on the uprights 18 of the framelland have thereon horizontal rollers 19 adapted to contact with the ring13 and also have thereon vertical rollers 20 and 21 adapted to contactwith the flanges 15 and 16.

, The floats 14 are secured to rods 22 which preferably have the outerend portions thereof rotatably mounted in the free end portions ofsupporting bars 23 which are suitportions of the rods 22 being rotatablymounted on brackets 24 which are suitably secured to the ring 13.

As shown, the floats 14 consist of closed bags 25 of canvas or othersuitable air-tight and watertight material which are secured to andadapted to fold against frames 26 when the bags are in deflatedcondition. The frames 26 are preferably formed semiannular and inclinedand gradually decreased in size from the upper or forward end thereof tothe lower or rear end thereof, and consist of semi-circular strips 27 atthe upper or forward part of the frame, and longitudinal strips 28'whichare suitably secured to the strips 27 and which are con- 29suitablysecured thereto. In this instance the bags 25 are formed ofstrips 30 which are cut bias and sewed together so that the bags wheninflated are substantially conical in shape and curve inwardly towardthe lower or rear' e nd thereof.

The ring is is preferabl driven by either i the line 7-7 of Fig. 6; Fig.8 is an enlarged V ably secured to the ring 13; the inner endneetedtogether by semi-circular crossstrips lower part of the frame 11 with awateror both of the rotary motors 31 which may be arranged opposite toeach other. The stationary shafts 32 of the motors 31 have one endthereof mounted on standards 33 on the cross bar 34 and have the otherend thereof mounted on brackets 35 suitably affiiied on the uprights 18.The driving connections between the motors'31 and the ring 13 mayconsist of upright shafts 36 mounted in bearings 37 and 38 on theuprights 18'; said shafts 36 having onthe upper end thereof pinions 391n mesh with bevel pinions 4O at-the ends of sleeves 41' which arerotatively mounted .on the stationary shafts 32, and having on the lowerend therew of pinions 42 immesh with teeth 43 on the ring 13. Thesleeves 41 have feathered thereon'parts t tadapted to be moved by levers45 to engage with parts 46 which are aflixed to the rotors of the motors31 and form clutchdevices. Suitable clutch devices 47 operated by levers48 may be provided on the shafts 36 whereby the ring 13 may beoperatively. connected with or disconnected from the shafts 36. at will.When theflying machine is of the formshown the direction of rotation ofthe floats leis pref? erably oppositeto that of the screw. 49 to ayoidany tendency of theflying machine to Whirl in flight. Suitable brakingmeans indieated at.50 may be provided to be operated at will tobean-againstthe ring 13. to-stop rotation ofthe I111 .7

f The means for inflating the: bags 25 byv ainpreferablv consistsofeflexible tubes, 51 connected between, the, bags. and a circular pipe52 which latteris suitably maunted' on the ring1'3 and. when desired maybaconnected to the air pump- 53,. by passing .the ends of afiexible,.tube, not shown-over nipplesfi and 55 on the. outlet .pi e 56i the air- ,pumpand the inletpip'e 5 ofthe circular pipe. '52. .The airpump 53 may consist of the cylinder -5 8i-which is. provided with asuitable inlet valve 59. and; outlet valve 60,-piston. 61, and pistonrod 62 which is pivotally conneeted with the piston 61 and with crankshaft 63; .A. suitableclutch 64 may be mounted on the crankshaft-.63.and may consist of female. member 65 fast on the crank shaft,-themale member 66,.whichhas the sprocket-Wheel 67 fast; thereon .and dsslidably mounted on the crank shaft, and an operating lever 68. whichhasone endthereof pivotally connected to a. bracket 69 suitably secured,to-lthe cylinder 58.- and has thereon yo wi 70 loosely fitt agre ve 0nthe ma b ,6 WA spr e lchain Zl passes around the'sprocket wheeh 657 andarounda sprocket wheel. 72 on. the roterigf. one ofthemotorsfil.

* fl-he imds 22 may be ro atec t9 adj he floats- 1.4:.-.inpositiombyimfi a f leve s 73 which are secured -to-.the-'.1:od s 22; andhave *e r em-Prm eh nsm ariap date fitin a y one of notches 75 insectors 76 to hold the floats in adjusted position; the levers beingadapted to be sprung away from the sectors to permit movement of thelevers.

The means for deflating the bags 25 pref erably consist of cords 77which are fastened to the rear or lower part of the frames 26 and. passthrough eyes 78 suitably afiixed on the sides of the bags which are freeof the frames 26 and through eyes 79 on the semicircular strips 27 andover sheaves 80 and past guide arms 81 to the reels 82 which latter havetheir shafts 83 journaled in standards 8 1 suitably secured tothebrackets24.

fThe flexible tube 'beingdisconnected from the nipples 5 t'and 55 andthe valve 86,0n t-he -intake,pipe 57 being opened, the reels 82 may beturned by handles85 on the shafts 83 to .Wind the cords 77 on the reelsand cause the cords 77 to draw. the-bags 25 into and against the frames26 whereupon the;shafts 83 may beloclred iniposition by means of pawls87 engaging with the ratchet wheels 88 whichare mounted'fast on theshafts .83.

It will be seenthatwhen, the bags-25v are deflated and drawn against theframes 26 the floats may be turned to substantially horizontal position,and rotated ,to .exert elevatmodifications thereof will readily occur.to
